IMPROVEMENT IN BLOTTERS.

Specification forming part of Letters Patent No. 223,193, dated December 30, 1879 application filed October 16, 1879.

To all whom it may concern:

Be it known that I, EMANUEL J. TRUM, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Blotting-Pad, of which the following is a specification.

The object of my invention is to provide an economical blottingpad.

The invention consists of a pad made of alternate sheets or layers of bibulous and nonbibulous paper, glued together at their ends in a manner to facilitate their ready separation.

The invention also consists in a new manner of connecting the pad with a wooden back.

In the accompanying drawings, Figure l is a side elevation of my improved blotting-pad. Fig. 2 represents my improvement applied to a double pad. Fig. 3 represents a modified form of the invention and Fig. 4 is a sec tional detail of my improvement.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the blotting-pad. It is composed of alternate sheets of thin blottingpaper a and a nonbibulous paper, I). The purpose of putting the sheets 1) between the blotting-sheets a is to prevent the ink taken up by sheets a from spreading beyond the sheet which is pressed on the ink. This arrangement enables me to use for the pad a thin blotting-paper instead of the thick paper heretofore used for pads.

The sheets a bare fastened together by gluing over their ends 0 c a strip, d, of thin tissuepaper, and then gluing over the tissue-paper a thicker paper, 0, the end f whereof is carried under the pad. By this arrangement the separation of the sheets a b is greatly facilitated, as the layer of tissue-paper d between the ends 0 c of the blotting-pad and the heavier paper 0 yields readily, and thus permits the sheets a b to be taken off without tearing.

The pad A, thus constructed, is applied to a piece of binders boa-rd, B, and glued thereto with the ends ff of end pieces, 0, between the pad and board. The ends g g of board B project beyond the ends of the blotting-pad A.

The pads A, constructed as above described, are used in connection with wooden backs (J, which have the surface at each end h chamfered off, as at z t. To the ends it h are fixed metal plates jj, which are bent to form flanges 70 In parallel to the chamfered portions 3 t.

The pads A are connected with the backsG by slipping the ends g of the board B between the flanges 70 and the chamfered portions i, as shown, whereby the pads are securely connected with the backs O and as the board B is longer than said back the pad is caused to assume a convex shape, as shown, thus giving said pad ample elasticity and a bearing-surface that permits it to be applied to a small part of the sheet to be blotted, and which also permits it to be rocked on the surface of the sheet in the act of blotting.

The blotting-pad may be arranged as a single pad, as in Fig. 1, or as a double pad, asin Fig. 2.

In Fig. 3 is shown a modified construction of the pad. In this modification the back 0 is provided with a convex surface, I, to which the pad A is glued, and the ends ccof the pad are attached to the ends of the back by carrying the ends f of pieces 0 over the ends of the back, and then gluing said ends f to the upper surface, m, of the back, as shown.

It is intended that the pads A, when connected with the board B, shall be made as a separate article, so that one back 0 can be used for any number of pads in succession.

The pads A and .back B may be made sufficiently large to be employed as a desk-padthat is, by making the pad and back sufficiently large to be placed on the desk and used as a surface for the writing-paper, 85c. Thus made, the pad can be secured to the desk or tableby driving tacks through the projecting portions of back B into the desk or table.

Having thus described in yin vention, I claim as new and desire to secure by Letters Patent 1. As an improvement in blotting-pads, the combination of the pad A, composed of alternate sheets of bibulous and non-bibulous paper, with the board B, as and for the purpose substantially as described.

2. In combination with sheets ab of pad A,

the strips (1 d and pieces 0 e, as and for the purpose substantially as described.
